The Life, Works and Codebreaking Machines of Marian Rejewsi

About

Discover the life and works of Marian Rejewski, the first to theorise the mathematical equations which would eventually lead to the breaking of the Enigma by the Allies.

During a historic and little-known meeting in Pyry, Warsaw, on the 25th and 26th July 1939, representatives of the Polish Government and Intelligence Services agreed to share with their British and French Allies information and machines related to their cryptographic analysis and deciphering of the German Enigma cipher. Included in this was the exceptional work of Polish codebreaker, Marian Rejewski, who was the first to theorise the mathematical equations which would eventually lead to the breaking of the Enigma by the Allies.

Join Robert Gawlowski, author of the biography The Untold Story of Marian Rejewski, who Passed the Baton to Alan Turing and Tim Flack, of King's College, Cambridge, as they explore the life, work and codebreaking machines of Rejewski, and their influence on the activities of Bletchley Park. 

Included in this event will be a demonstration of a fully functional replica Cyclometer – the first electromechanical device created by Rejewski to aid in the daily breaking of Enigma keys, and which was succeeded by the Polish Bomba, the forerunner to Alan Turing's Bombe.

Tickets for event only: £15
